Description

Technical Field

[0001] The present application relates to the field of containers, and in particular to a nozzle bottle. Background Art

[0002] The speed of milk coming out of the nipple of a feeding bottle is related to the size of the liquid outlet hole of the nipple, the sucking strength of the baby, the volume of milk in the bottle and the speed of air entering the bottle. The liquid outlet hole and air inlet valve of the existing nipple of feeding bottles are fixed. Although customers can choose nipples with different liquid outlet hole sizes to change the speed of liquid outflow from the nipple, once the nipple is determined, its liquid outflow speed is fixed. For some babies with slow swallowing speed, sometimes even if the nipple with the smallest liquid outlet hole is selected, the swallowing speed is often lower than the liquid outflow speed, which causes the baby to choke on milk.

[0035] The terms "first", "second", etc. in the specification and claims of this application and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally includes steps or units that are not listed, or optionally includes other steps or units inherent to these processes, methods, products or devices.

[0036] The technical solutions in the embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0037] It should be noted that, for the convenience of explanation, in the embodiments of the present application, the same figure marks represent the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments.

[0038] The speed of milk coming out of the nipple of a feeding bottle is related to the size of the liquid outlet hole of the nipple, the sucking strength of the baby, the volume of milk in the bottle and the speed of air entering the bottle. The liquid outlet hole and air inlet valve of the existing nipple of feeding bottles are fixed. Although customers can choose nipples with different liquid outlet hole sizes to change the speed of liquid outflow from the nipple, once the nipple is determined, its liquid outflow speed is fixed. For some babies with slow swallowing speed, sometimes even if the nipple with the smallest liquid outlet hole is selected, the swallowing speed is often lower than the liquid outflow speed, which causes the baby to choke on milk.

[0039] See also Figure 1 and Figure 2 The embodiment of the present application provides a nozzle bottle 100, the nozzle bottle 100 includes a bottle assembly 10 and a ventilation mechanism 20, the bottle assembly 10 includes a bottle body 11 and a cover body 12, the cover body 12 and the bottle body 11 enclose a receiving cavity 13, the cover body 12 includes a nozzle 121; the ventilation mechanism 20 is located in the receiving cavity 13, and is used to control the connection and closure of the receiving cavity 13 with the external environment, the ventilation mechanism 20 includes a ventilation pipe 21 and an adjustment component 22, the One end of the vent pipe 21 is connected to the bottle assembly 10 and communicates with the outside of the bottle assembly 10, and the other end of the vent pipe 21 is installed on the regulating assembly 22. When the bottle assembly 10 is in a normal pressure state, the regulating assembly 22 closes the vent pipe 21. When the bottle assembly 10 is in a negative pressure state, the regulating assembly 22 opens the vent pipe 21. The regulating assembly 22 is also used to adjust the air intake rate of the vent pipe 21 when the bottle assembly 10 is in a negative pressure state.

[0040] The nozzle bottle 100 of the embodiment of the present application may be, but is not limited to, a fluid container such as a milk bottle or a straw bottle, and is used to hold fluids such as water and milk. It should be noted that in the drawings of the present application, the nozzle bottle 100 is illustrated by taking a milk bottle as an example, which should not be understood as a limitation on the nozzle bottle 100 of the present application. The nozzle bottle 100 of the embodiment of the present application may also be a fluid container of other shapes or forms.

[0041] Optionally, the nozzle 121 may be, but is not limited to, a pacifier, a straw, etc.

[0042] Optionally, the bottle body 11 and the cover body 12 can be fixedly connected or detachably connected. Optionally, the ventilation assembly and the bottle assembly 10 can be separately arranged, detachably connected or fixedly connected.

[0043] It should be noted that the vent pipe 21 refers to a pipe body having a channel, for example, a pipe body that allows gas or liquid to pass through.

[0044] Optionally, the suction nozzle 121 has a liquid outlet hole 1211. The suction nozzle 121 is used to suck fluid from the accommodating cavity 13.

[0045] It should be noted that when the bottle assembly 10 is in a normal pressure state, the regulating assembly 22 closes the vent pipe 21; when the nozzle bottle 100 stores fluid and sucks, air is sucked from the nozzle 121 to generate a negative pressure in the bottle assembly 10, so that the atmospheric pressure in the bottle assembly 10 is lower than the external atmospheric pressure. Under the action of the external atmospheric pressure, the regulating assembly 22 opens the vent pipe 21, so that gas enters the accommodating chamber 13 from the outside (the gas flows to the direction shown in FIG. 1 ). Figure 1 In addition, the regulating component 22 can also adjust the air intake rate of the air intake pipe, thereby adjusting the fluid flow rate of the suction nozzle 121.

[0046] The nozzle bottle 100 of the embodiment of the present application includes a bottle assembly 10 and a ventilation mechanism 20, wherein the ventilation mechanism 20 is located in the accommodating chamber 13, and is used to control the connection and closure between the accommodating chamber 13 and the external environment, and the ventilation mechanism 20 includes a ventilation pipe 21 and an adjusting component 22, one end of the ventilation pipe 21 is connected to the bottle assembly 10 and is connected to the outside of the bottle assembly 10, and the other end of the ventilation pipe 21 is installed on the adjusting component 22, when the bottle assembly 10 is in a normal pressure state, the adjusting component 22 closes the ventilation pipe 21, and when the bottle assembly 10 is in a negative pressure state, the adjusting component 22 opens the ventilation pipe 21, and the adjusting component 22 is also used to adjust the air intake rate of the ventilation pipe 21 when the bottle assembly 10 is in a negative pressure state. The regulating component 22 can not only control the opening and closing of the vent tube 21, but also adjust the air intake rate of the vent tube 21, thereby adjusting the flow rate of the fluid flowing out of the suction nozzle 121, so that the suction nozzle bottle 100 can be better suitable for people of different ages. When used for infants, it can better prevent infants, especially infants with a slow swallowing speed, from choking on milk or water.

[0047] See also Figure 3 and Figure 4In some embodiments, the vent pipe 21 has a first opening 211 and a second opening 212, the first opening 211 is connected to the outside of the bottle assembly 10, and the second opening 212 is connected to the accommodating chamber 13; the adjusting assembly 22 includes a first adjusting member 221 and a second adjusting member 222 connected to each other, the first adjusting member 221 is arranged at the second opening 212, and is used to open or close the second opening 212; when the bottle assembly 10 is in a normal pressure state, the first adjusting member 221 abuts against the second opening 212 of the vent pipe 21 to close the second opening 212; when the bottle assembly 10 is in a negative pressure state, the first adjusting member 221 and the second opening 21 2 is arranged at an interval to connect the second opening 212 with the accommodating chamber 13; the second adjusting member 222 is located on the side of the first adjusting member 221 away from the second opening 212 and can be movably connected to the vent pipe 21, and the second adjusting member 222 can move toward or away from the second opening 212 compared with the vent pipe 21. When the second adjusting member 222 moves toward or away from the second opening 212 and the bottle assembly 10 is in a negative pressure state, the first adjusting member 221 moves toward or away from the second opening 212, thereby adjusting the interval distance between the first adjusting member 221 and the second opening 212 to adjust the air intake rate of the ventilating mechanism 20.

[0048] It can be understood that when the bottle assembly 10 is in a negative pressure state, the first adjusting member 221 moves in a direction away from the second opening 212, thereby maintaining a certain distance from the second opening 212, and then opening the second opening 212, so that gas from the external environment enters the accommodating chamber 13. When the pressure in the bottle assembly 10 returns to a normal pressure state, the first adjusting member 221 moves in a direction close to the second opening 212, so that the first adjusting member 221 abuts against the second opening 212 again, and the second opening 212 is closed again.

[0049] It can be understood that the second opening 212 , the first adjusting member 221 and the second adjusting member 222 are arranged in sequence.

[0050] It should be noted that when the second adjusting member 222 moves toward the direction close to the second opening 212, when the bottle assembly 10 is in a negative pressure state, under the condition of the same negative pressure, the distance between the first adjusting member 221 and the second opening 212 will become smaller, thereby reducing the air intake rate of the second opening 212, and further reducing the fluid outflow rate of the suction nozzle 121; on the contrary, when the second adjusting member 222 moves toward the direction away from the second opening 212, when the bottle assembly 10 is in a negative pressure state, under the condition of the same negative pressure, the distance between the first adjusting member 221 and the second opening 212 will become larger, thereby increasing the air intake rate of the second opening 212, and further increasing the fluid outflow rate of the suction nozzle 121. Therefore, by adjusting the relative distance between the second adjusting member 222 and the second opening 212, the distance between the first adjusting member 221 and the second opening 212 when the bottle assembly 10 is in a negative pressure state can be adjusted, thereby adjusting the air intake rate of the second opening 212, and finally changing the fluid outflow rate of the suction nozzle 121.

[0051] In this embodiment, by cooperating with the first adjusting member 221, the second adjusting member 222 and the vent tube 21, the relative distance between the second adjusting member 222 and the second opening 212 can be adjusted. Therefore, when the bottle assembly 10 is in a negative pressure state, the distance between the first adjusting member 221 and the second opening 212 can be adjusted, thereby adjusting the opening or size of the second opening 212, and further adjusting the fluid outflow speed of the suction nozzle 121. In this way, when the fluid outflow speed of the suction nozzle 121 does not match the swallowing speed of the user, it can be adjusted through the adjustment mechanism without replacing the suction nozzle 121 with a larger liquid outlet hole 1211, thereby greatly improving the user experience.

[0052] See also Figure 5 and Figure 6 In some embodiments, the first adjusting member 221 is protruded from one side of the second adjusting member 222, the vent pipe 21 includes a connected air intake pipe 213 and a connecting pipe 214, the air intake pipe 213 has the first opening 211 at one end away from the connecting pipe 214, the air intake pipe 213 has the second opening 212 at one end connected to the connecting pipe 214, the radial dimension of the connecting pipe 214 is larger than the radial dimension of the air intake pipe 213, the first adjusting member 221 is penetrated by the connecting pipe 214, the second adjusting member 222 can rotate the end of the connecting pipe 214 away from the air intake pipe 213 and is partially sleeved on the connecting pipe 214, the second adjusting member 222 has a connecting hole 2221 connected to the accommodating chamber 13.

[0053] It can be understood that the air inlet pipe 213 and the connecting pipe 214 have a pipe body of a channel.

[0054] Optionally, the air intake pipe 213 and the connecting pipe 214 may be an integrated structure, and the air intake pipe 213 and the connecting pipe 214 are different parts of the same component.

[0055] Optionally, the number of the communicating holes 2221 may be one or more. When the number of the communicating holes 2221 is plural, the multiple communicating holes 2221 are arranged at intervals.

[0056] It should be noted that the inner diameter of the connecting pipe 214 is larger than the inner diameter of the air intake pipe 213 , and the outer diameter of the connecting pipe 214 is also larger than the outer diameter of the air intake pipe 213 .

[0057] Optionally, the connecting pipe 214 is connected to one end of the air inlet pipe 213 , and the size of the connecting pipe 214 is gradually reduced.

[0058] It should be noted that when the bottle assembly 10 is in a normal pressure state, the first adjusting member 221 abuts against the connecting tube 214 and closes the second opening 212 , and when the bottle assembly 10 is in a negative pressure state, there is a gap between the first adjusting member 221 and the second opening 212 and the connecting tube 214 .

[0059] It should be noted that when the bottle assembly 10 is in a negative pressure state, external air enters from the first opening 211 , and enters into the accommodating chamber 13 through the second opening 212 , the connecting pipe 214 and the communicating hole 2221 .

[0060] It can be understood that the communicating hole 2221 communicates with the accommodating cavity 13 and the connecting pipe 214 .

[0061] In this embodiment, the radial dimension of the connecting tube 214 is designed to be larger than the radial dimension of the air inlet pipe 213, so that the connection between the connecting tube 214 and the air inlet pipe 213 forms a trumpet shape, and the first adjusting member 221 is arranged in the connecting tube 214, so that when the bottle assembly 10 is in a normal pressure state, the first adjusting member 221 can better support the connecting tube 214 and close the second opening 212, and when the bottle assembly 10 is in a negative pressure state, the second opening 212 has a more controllable opening, and through the limiting effect of the connecting tube 214, during the repeated inhalation process, the first adjusting member 221 is less likely to be misplaced, thereby improving the service life of the ventilation mechanism 20.

[0062] In some embodiments, the first adjusting member 221 is an elastic member. When the bottle assembly 10 is in a normal pressure state, the first adjusting member 221 is in a relaxed state or a compressed state. By adjusting the distance between the second adjusting member 222 and the second opening 212, the compression degree of the first adjusting member 221 is adjusted, and then the distance between the first adjusting member 221 and the second opening 212 is adjusted when the bottle assembly 10 is in a negative pressure state, so as to change the air intake rate at the second opening 212.

[0063] It should be noted that when the suction nozzle 121 inhales, negative pressure is generated in the bottle assembly 10, so that the atmospheric pressure in the bottle assembly 10 is less than the external atmospheric pressure. Under the action of the external atmospheric pressure, the first adjusting member 221 is compressed, so that a gap is generated between the first adjusting member 221 and the second opening 212, so that the gas enters the accommodating chamber 13. When the second adjusting member 222 moves toward the direction close to the second opening 212, the degree of compression of the first adjusting member 221 increases, and it has a greater resilience. At this time, if the suction nozzle 121 is inhaled again, under the condition that the suction force remains unchanged, since the first adjusting member 221 has a greater resilience at this time, the compression of the first adjusting member 221 by the external atmospheric pressure will be reduced, so that the distance between the first adjusting member 221 and the second opening 212 is reduced, and then the air intake rate at the second opening 212 is reduced, thereby adjusting the speed of liquid discharge from the suction nozzle 121.

[0064] It can be understood that the first adjusting member 221 is elastic and will undergo elastic deformation under the action of an external force. After the external force disappears, the first adjusting member 221 will recover its deformation and return to its initial state.

[0065] It should be noted that the relaxed state refers to a state that is neither stretched nor compressed, that is, a balanced state without any external force.

[0066] In this embodiment, by adjusting the distance between the second adjusting member 222 and the second opening 212, the compression degree of the first adjusting member 221 is adjusted, and then the distance that the first adjusting member 221 moves away from the second opening 212 when the bottle assembly 10 is in a negative pressure state is adjusted, so as to adjust the air intake rate of the second opening 212, and then adjust the speed of liquid discharge from the liquid outlet 1211 of the suction nozzle 121. Thus, the suction nozzle bottle 100 can be better suitable for people of different ages. When it is used for infants, it can better prevent infants, especially infants with slow swallowing speed, from choking on milk or water. When the fluid outflow speed of the suction nozzle 121 does not match the swallowing speed of the user, the liquid outflow speed of the liquid outlet 1211 can be adjusted by adjusting the distance between the second adjusting member 222 and the second opening 212, without replacing the suction nozzle 121 with a larger liquid outlet 1211, which greatly improves the user experience.

[0067] The nozzle bottle 100 of the embodiment of the present application includes a bottle assembly 10 and a ventilation mechanism 20, wherein the ventilation mechanism 20 is located in the accommodating chamber 13, and is used to control the connection and closure between the accommodating chamber 13 and the external environment, and the ventilation mechanism 20 includes a ventilation pipe 21 and an adjusting component 22, one end of the ventilation pipe 21 is connected to the bottle assembly 10 and is connected to the outside of the bottle assembly 10, and the other end of the ventilation pipe 21 is installed on the adjusting component 22, when the bottle assembly 10 is in a normal pressure state, the adjusting component 22 closes the ventilation pipe 21, and when the bottle assembly 10 is in a negative pressure state, the adjusting component 22 opens the ventilation pipe 21, and the adjusting component 22 is also used to adjust the air intake rate of the ventilation pipe 21 when the bottle assembly 10 is in a negative pressure state. The regulating component 22 can not only control the opening and closing of the vent tube 21, but also adjust the air intake rate of the vent tube 21, thereby adjusting the flow rate of the fluid flowing out of the suction nozzle 121, so that the suction nozzle bottle 100 can be better suitable for people of different ages. When used for infants, it can better prevent infants, especially infants with a slow swallowing speed, from choking on milk or water.

[0068] See also Figure 7 and Figure 8 In some embodiments, the second adjusting member 222 has a first position relative to the second opening 212 (eg Figure 7 ) and the second position (as shown Figure 8 As shown), the first position is closer to the second opening 212 than the second position, and when the second adjusting member 222 is in the first position, the first adjusting member 221 is in a compressed state; when the second adjusting member 222 is in the second position, the first adjusting member 221 is in a compressed state or a relaxed state.

[0069] It can be understood that the second adjusting member 222 can move between a first position and a second position relative to the second opening 212 .

[0070] It should be noted that the first adjusting member 221 may be in a relaxed state only when the second adjusting member 222 is in the second position, but preferably, when the second adjusting member 222 is in the second position, the first adjusting member 221 is in a compressed state. When the second adjusting member 222 is in the second position and the first adjusting member 221 is in a compressed state, when the bottle assembly 10 is in a normal pressure state, the first adjusting member 221 also has a certain elastic restoring force, which can better resist and close the second opening 212, thereby better ensuring the airtightness of the nozzle bottle 100.

[0071] It should be noted that when the second adjusting member 222 is between the first position and the second position, the first adjusting member 221 is in a compressed state. The closer the second adjusting member 222 is to the first position, the higher the compression degree of the first adjusting member 221 is.

[0072] In this embodiment, when the second adjusting member 222 is in the first position, the first adjusting member 221 is in a compressed state; when the second adjusting member 222 is in the second position, the first adjusting member 221 is in a compressed state or a relaxed state. In this way, when the bottle assembly 10 is in a normal pressure state, the first adjusting member 221 always closes the second opening 212, and it is not easy to leak liquid from the vent pipe 21; the second opening 212 will only be opened when liquid is sucked from the suction nozzle 121.

[0073] See also Fig. 9 In some embodiments, the first adjusting member 221 includes a first elastic portion 2211 and a second elastic portion 2212 that are connected to each other. The radial dimension of the first elastic portion 2211 is greater than the radial dimension of the second elastic portion 2212. When the bottle assembly 10 is in a normal pressure state, the first elastic portion 2211 abuts against the second opening 212, and the end of the second elastic portion 2212 that is away from the first elastic portion 2211 is connected to the second adjusting member 222.

[0074] Optionally, the inner wall of the connecting tube 214 near the second opening 212 is a curved surface, and the surface of the first elastic part 2211 facing the second opening 212 is a curved surface. In a specific embodiment, the inner wall of the connecting tube 214 near the second opening 212 is a spherical surface, and the surface of the first elastic part 2211 facing the second opening 212 is a spherical surface.

[0075] Optionally, the radial dimension of the first elastic portion 2211 is greater than the radial dimension of the second opening 212 , so that when the first elastic portion 2211 abuts against the second opening 212 , the first elastic portion 2211 can better close the second opening 212 .

[0076] Optionally, the first elastic portion 2211 and the second elastic portion 2212 may be an integral structure; or may be a separate structure, which are first manufactured separately and then assembled together.

[0077] It can be understood that when the suction nozzle 121 inhales air, negative pressure is generated in the bottle assembly 10, so that the atmospheric pressure in the bottle assembly 10 is lower than the external atmospheric pressure. Under the action of the external atmospheric pressure, the first elastic part 2211 and the second elastic part 2212 are compressed, so that a gap is generated between the first elastic part 2211 and the second opening 212, thereby allowing gas to enter the accommodating cavity 13. When the second adjusting member 222 moves toward the direction approaching the second opening 212, the compression degree of the first elastic portion 2211 and the second elastic portion 2212 increases, and they have a greater resilience. At this time, if air is inhaled through the suction nozzle 121 again, under the condition that the suction force remains unchanged, since the first elastic portion 2211 and the second elastic portion 2212 have a greater resilience, the compression of the first elastic portion 2211 and the second elastic portion 2212 by the external atmospheric pressure will be reduced, thereby reducing the distance between the first elastic portion 2211 and the second opening 212, and further reducing the air intake rate at the second opening 212, thereby adjusting the liquid discharge speed of the suction nozzle 121.

[0078] Optionally, the material of the first elastic part 2211 may be but is not limited to silicone. Optionally, the shape of the first elastic part 2211 may be hemispherical, and the first elastic part 2211 may be solid or hollow.

[0079] Optionally, the material of the second elastic part 2212 may be, but is not limited to, silicone. Optionally, the second elastic part 2212 may be, but is not limited to, an elastic column, a spring, and the like.

[0080] Optionally, the elastic modulus of the first elastic portion 2211 is smaller than the elastic modulus of the second elastic portion 2212, so that the second elastic portion 2212 can better support the first elastic portion 2211. When the bottle assembly 10 is in a normal pressure state, the second elastic portion 2212 can better support the first elastic portion 2211, so that the first elastic portion 2211 tightly presses against the second opening 212, thereby better sealing the second opening 212.

[0081] Optionally, the average density of the first elastic part 2211 is less than the density of water. Thus, when water or milk is placed in the accommodating cavity 13, the buoyancy of the first elastic part 2211 is greater than the gravity of the first elastic part 2211, so that the first elastic part 2211 is better supported against the second opening 212 due to the buoyancy and the second opening 212 is sealed.

[0082] In this embodiment, the first adjusting member 221 includes a first elastic portion 2211 and a second elastic portion 2212 connected to each other, and the radial dimension of the first elastic portion 2211 is greater than the radial dimension of the second elastic portion 2212, so that when the first elastic portion 2211 abuts against the second opening 212, the first elastic portion 2211 can better close the second opening 212. At the same time, through the cooperation of the first elastic portion 2211 and the second elastic portion 2212, when the bottle-saving assembly 10 is in a negative pressure state, the distance between the first elastic portion 2211 and the second opening 212 has a larger adjustment range, so that the flow rate of the liquid flowing out of the suction nozzle 121 can be adjusted in a larger range.

[0083] Please see again Figure 7 and Figure 8 In some embodiments, the end of the connecting pipe 214 away from the air inlet pipe 213 has an external thread; the second adjusting member 222 is bent and connected to the adjusting portion 2222 and the sleeve portion 2223, the adjusting portion 2222 has the connecting hole 2221, the sleeve portion 2223 surrounds the setting of the adjusting portion 2222, the sleeve portion 2223 has an internal thread, and the external thread is threadedly connected to the internal thread.

[0084] Optionally, corresponding scales or numbers can be provided on the outer surface of the connecting tube 214 or the sleeve 2223 to facilitate user identification and adjustment. For example, an arrow is provided on one of the connecting tube 214 and the sleeve 2223, and a number is provided on the other. The arrow pointing to the corresponding number represents the position suitable for babies of the corresponding age or month.

[0085] In a specific embodiment, when the second adjusting member 222 is screwed to the bottom (at this time, the distance between the second adjusting member 222 and the second opening 212 is the smallest, and the compression degree of the first adjusting member 221 is the largest), the position corresponding to the connecting tube 214 or the sleeve portion 2223 is marked with 0, and along the direction of loosening the second adjusting member 222, the values ​​1, 2, 3, 4, etc. are marked in sequence. In this way, when the user uses it, the corresponding scale can be quickly adjusted to the age of the baby, so that the nozzle 121 has a suitable fluid flow rate. When the air intake rate is felt to be too low, just loosen the second adjusting member 222 a little; when the air intake rate is felt to be too high, just tighten the second adjusting member 222 a little.

[0086] In this embodiment, the threaded connection between the external thread of the connecting tube 214 and the internal thread of the sleeve portion 2223 facilitates the installation of the second adjusting member 222. In addition, the distance between the second adjusting member 222 and the second opening 212 can be adjusted by tightening or loosening the second adjusting member 222, thereby adjusting the degree of compression of the first adjusting member 221, and further adjusting the gap between the first adjusting member 221 and the second opening 212 when the bottle assembly 10 is under negative pressure, thereby adjusting the air intake rate at the second opening 212, thereby adjusting the flow rate of the fluid flowing out of the suction nozzle 121.

[0087] See also Fig.10 In some embodiments, the ventilation pipe 21 further includes a first limiting member 215 , which is disposed at one end of the external thread of the connecting pipe 214 close to the air inlet pipe 213 , and is used to limit the first position of the second adjusting member 222 .

[0088] In this embodiment, a first limit member 215 is provided at an end of the external thread closer to the air inlet pipe 213, so that the second adjusting member 222 is limited to prevent the user from continuing to tighten the second adjusting member 222 after it is screwed to the first position, causing the second adjusting member 222 to be screwed too much, and the distance between the second adjusting member 222 and the second opening 212 is too small. Therefore, when the bottle assembly 10 is in a negative pressure state, the first adjusting member 221 still abuts against the second opening 212, affecting the air intake of the second opening 212, thereby affecting the use of the nozzle bottle 100.

[0089] In some embodiments, the ventilation pipe 21 further includes a second limiting member 216 , which is disposed at an end of the external thread of the connecting pipe 214 away from the air inlet pipe 213 , and is used to limit the second position of the second adjusting member 222 .

[0090] In this embodiment, a second limit member 216 is provided at an end of the external thread further away from the air inlet pipe 213, so that the second adjusting member 222 is limited to prevent the user from continuing to loosen the second adjusting member 222 after it is screwed to the second position, causing the second adjusting member 222 to be screwed too much, and the distance between the second adjusting member 222 and the second opening 212 is too large. When the bottle assembly 10 is in a normal pressure state, there is a gap between the first adjusting member 221 and the second opening 212, so that the liquid in the bottle assembly 10 leaks out from the ventilation mechanism 20, affecting the user experience.

[0091] Please see again Fig. 9In some embodiments, the second elastic portion 2212 has a through hole 2213 at one end away from the first elastic portion 2211, and the second adjusting member 222 also includes a column portion 2224, the column portion 2224 and the sleeve portion 2223 are arranged on the same side of the adjusting portion 2222, and the column portion 2224 is located in the sleeve portion 2223, the column portion 2224 is penetrated by the through hole 2213, and the column portion 2224 and the second elastic portion 2212 are interference fit.

[0093] It can be understood that the second elastic portion 2212 is sleeved on the outer circumference of the column portion 2224 .

[0094] In this embodiment, by providing a through hole 2213 on the second elastic part 2212 and providing a column part 2224 on the second adjusting member 222, the second elastic part 2212 is sleeved on the outer periphery of the column part 2224, which facilitates the assembly of the first adjusting member 221 and the second adjusting member 222, simplifies the assembly process of the ventilation mechanism 20, and reduces the cost of the ventilation mechanism 20. In addition, this is also conducive to the disassembly and cleaning of the ventilation mechanism 20.
